Rabbit IgG, polyclonal - Isotype Control images

  • Histogram showing the fluorescence signal for ADRB2-FITC in PBMCs compared to an Isotype control.

    PBMCs were generated from freshly-drawn blood from healthy human donors. After staining with antibodies against ADRB2 (ab36956) or an isotype control (ab37415), cells were incubated with FITC-labeled secondary anti-rabbit-IgG antibody, and ADRB2 expression was assessed by flow cytometry.

  • ChIP-qPCR for H3K36me2 on the BTF3 locus in NTKO and TKO cells. Methylation enrichment was tested 5 kb upstream of the TSS (5′) and at the TSS (right). ab37415 was used as the isotype contol.
